Subject: [PATCH] parse.y: fix compilation for non-multibyte builds

Builds configured with --disable-multibyte or when the toolchain does
not have WCHAR support would encounter a compile error due to an
undeclared reference to shell_input_line_property in shell_getc.

Add a HANDLE_MULTIBYTE guard to conditionally compile the block that
references shell_input_line_property in shell_getc as it's only declared
when HANDLE_MULTIBYTE is defined.
